Will it continue to charge from the solar panel while it is charging from the wall ??

I can't tell that it charges from solar at all. It is advertised and sold as 30,000mah but when it was received, it is 10,000mah. It does not chage my phone or my Ipad. I will be returning it. But, to answer your question, I do not know if it charges both ways simultaneously, because the instructions are so poor, in gibberish English.

Yes! I've charged my phone or my iPad while it was plugged into the wall! Just don't forget to push the on button or else it won't charge whatever is plugged into it

If the battery already has a charge it would be like using it white plugged into the wall... Just not as good. The solar charger is more like a trickle charge. It will keep the battery charged longer than if it wasn't charging it. Thus is assuming your battery can drain and charge at the same time

It seems like it charges some. Mine died on me after hours of being on. Didn't think about turning off. Latter next day I noticed it was on. One note though The solar panel is small and not of the latest technology. I doubt you would get as good of charge if left on. Hope this helps some.

Actually, if you set the output voltage and amperage limits using the trimpots. Once set, it will govern the output to whichever limit it bumps into first. So if you set the max charging current to say 500ma @ 24v then it will reduce the voltage to stay at/under 500ma while never allowing the voltage to exceed 24v. In theory, if you set the voltage to just under you battery's fully charged voltage and then set the current to a sane limit it should float when charged. For 'back' feeding to the solar panel, just put a diode in-line on the output. You can think of diodes like little check valves. ;)

I dont know? I only charge the solar into the wall with the ac charge sorry if i didnt complete you answer

It does charge from the wall, as well as from a USB attached to a computer.

I have only had to use it a few times so far, but even out of the sun it appears to charge as long as the power cell has some juice stored in it. I would suggest contacting the manufacturer to be sure, especially if you really need to rely on it for a longer trip.

This is Levin Service. Thanks for your question and concern to Solstar. This device has two types of charging: one is conventional charging via outlet; the other is charging by the solar panel which can convert sunlight into power. We suggest that please do not over depend on sunlight, but it will surely do a great job in case of emergency like there is no wall charger by your side or only sunlight left around.

I think it charged it a couple times. Honestly I didn't end up leaving it on there the whole time. So I'm not exactly sure. But it definitely charged it just like plugging to the wall

Yes, you will be able to use this as if it is plugged directly into the wall. It will not only power it but also charge it slowly while you are using it.

It will NOT charge a battery from zero. If the battery is in good condition, and fully charged, the solar "tender" will keep it topped off.

I keep my light in a window to keep it charged, I've never charged with USB, so sorry, I'm not sure. I would assume it would. Mine seems to show the red light only when the solar screen is exposed to light (any kind), showing it's charging.

Yes, you can use it while it's charging. Not sure about a wall charger, but it should work. We charge ours with a laptop while in use. It lasts for quite a long time after charging.

Yes it will charge it. I charged mine for about 5 hours, after 5 hours unplug the charger from the wall but leave the battery clips connected, if the light is green is charged, if it is yellow, plug it back and charge for another 2 hours.

No, it requires the sun to charge and does not store charge. It won't contribute to draining your battery so you can keep it plugged in.

That is a good question. I am inclined to say yes but at half the rate. Based on my experience it would be like using a solar panel at half the wattage, it would only maintain a battery as opposed to charging. good luck.
